IMPROVEMENT iN PLAITlNG-MACHINES.

Specification forming part of Letters Patent No. M260, dated July 10, 18775 application filed October 26, 1876.

To all whom it may concern:

Beit known that I, JOHN H. BROWN, of the city of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Plaiting-Machines, of which the following is a specification, reference being had to the accompanying drawings, forming part of the same.

Similar letters refer to like parts.

The object of my invention is to produce asimple and improved plaiting machine for making trimming for ladies7 wearing-apparel, it being an improvement on my patent plaiting-machine patented July 1l, 1876, No.

179,7 685 and consists of a novel arrangement for heating the lower roller, and an improved method of adjusting the throw of the feedoperating crank, as hereinafter described.

Figure l is an end elevation. Fig. 2 is a transverse section of the lower roller, showing my improved mode of applying the heat. Fig. 3 is a front elevation of the adjustable crank-block for regulatingl the throw of the feed. Fig. 4 is a transverse section of the adjustable crank-block, showing the set-screw w and crank-pin w.

A is the frame of the machine. B B are stay-bolts, for connecting the sides A together. C is the lower roller; D, the top roller. E is an elastic covering for the top roller. G is a gear on the top roller. F is a gear on the lower roller. H is a hollow rock-shaft passing through the roller C. I is a conical inlet-tube, screwed into the hollow rock-shaft H, for the admission of gas and air into the hollow rock-shaft H. J is a gas-burner, held between projections on the inside of the conical tube I. K is the shaft of the top or feed roller. L is a lever, pivoted at M for attaching and detaching the roller D from the roller G. N is a spring, for giving the necessary pressure on the top roller through the lever L. O is a projection from the side of the frame A, from which the spring N acts. P is a carnshaft, for detaching the roller l) from the roller C 5 Q, a lever, for operating the cam-shaft P 5 S, a disk on the main shaft R, with beveled slot, for reception of sliding block; s, an adjustable sliding block, for regulating the throw of the feed-roller. T is a crank on the main shaft R, for operating the plaiting-blade Y through the connecting-rod u and lever d; Y, the connecting-rod, for operating the feed by the adjustable block s; W, a ratchet-lever,

for operating the wheel Z by the pawl f. wis a sctvscrew, pinned to the crank-lever X, for securing in position the adjustable block s, and forming a crank-pin at fw, for the connecting' rod V. X is a crank-lever, for rotating the machine. a are radius-bars, rigidly attached to the hollow shaft H 5 b, a radius, on which the plaitingblade bar operates; d, a lever, for operating the plaiting-blade bar; e, a slot in the lever d, for adjusting the plaitingblade 5 c, a lug on a, on which the lever d strikes to operate a ou the backward movement of the plaiting-blade-Y. f is a ratchet-pawl, for operating the ratchet-wheel Z. h h are holes in the hollow rock-shaft H, from which the gas for heating the roller O is consumed. z i i are tension bars, through which the material passes to the plaiting-blade Y5 s', an adjustable block in the disk S5 w, a set-screw, for holding the adjustable block in position. t are holes for adjusting the throw of the plaiting-blade. u u u are holes for adjusting the position of the plaiting-blade Y.

When motion is given to the machine the plaiting-blade Y receives a forward and back motion from the crank 'I and connecting-rod U. In the forward motion the blade Y presses the material iirnlly on the roller C; a forward movement ol" the blade takes place, making a plait ofthe desired width, which is forced between the/rollers O and D. The plait being now formed, the rollers receive motion from the cranklever X, crankpin W, connectingrod V, and ratchet-wheel Z, carrying the plait through the rollers. The plaiting-blade returns to its startingpoint-e to form another plait.

I am aware that a sliding block is old in plaitingmachines for changing the throw of the operating-crank, and such I do not claim 5 but What I claim is- 1. In a plait-ingmachine the hollow rockshaft H and arms a a, arranged to operate as described, for the purpose set forth.

2. The combination of the set-screw fw and crank-pin fw with the sliding block s, constructed and arranged substantially as and for the purpose set forth.

JOHN H. BROWN.
